Maryland health officials are responding to a growing number of measles cases, with outbreaks now declared in three counties and local health departments working to limit further spread and expand access to vaccination.
The Maryland Department of Health (MDH) has declared a measles outbreak in St. Mary’s, Carroll, and Cecil counties after confirming 14 new cases among Maryland residents. The Department reports that no public exposures have been identified and that there is currently no evidence of widespread community transmission, with most cases occurring among household contacts.
Maryland has recorded 31 confirmed measles cases in 2026, including 27 cases confirmed since July 15. Those 27 cases involve unvaccinated residents in St. Mary’s (13), Carroll (8), Cecil (5), and Charles (1) counties. Four additional cases were confirmed earlier this year in Anne Arundel, Baltimore, and Prince George’s counties.
The Department is working with local health departments in affected communities to respond to cases, support residents, and increase access to vaccination. More than 106,000 MMR vaccines have been administered statewide in 2026, including more than 24,000 since July 1.
From the press release:
Measles is highly contagious and we are actively working with healthcare professionals and local health departments to support impacted communities, respond to cases and mitigate further spread. The overall risk remains low if you are fully vaccinated, said Maryland Department of Health Secretary Dr. Meena Seshamani.
Residents can check their immunization records through their health care provider or Maryland’s MyIR system. Local health departments are offering MMR and other vaccines and working with community partners to make information and vaccination opportunities available. Standard health insurance plans typically cover the MMR vaccine, while programs such as Vaccines for Children and the Maryland Vaccine Program can provide access for eligible uninsured or underinsured residents.
The Department continues to provide guidance to health care providers and facilities and is supporting case investigations through the State Public Health Laboratory. Residents who believe they may have been exposed to measles should contact their health care provider or local health department before seeking in-person care so appropriate precautions can be taken.
